CRUSHER.

SPECIFICATION forming part of Letters Patent No.758,735, dated May 3, 1904.

Application filed June 13, 1903. Serial No. 161,248. (No model.)

To all who/n it 71mg/ concern:

Be it known that I, JAMES IV. BOILEAU, a

citizen of the United States, residing at De-` troit, in the county of rayne and State of Michigan, have invented certain new and useful Improvements in Crushers, of which the following is a specification, reference being had therein to the accompanying' drawings.

The invention relates to rock-Crushers; and it consists in the peculiar construction, arrangement, and combination of parts, as hereinafter set forth.

In the drawings, Figure 1 is an end eleva tion of the machine. Fig.4 2 is a longitudinal section therethrough, and Fig. 3 is a crosssection.

The machine belongs to crushers of that type in which the material is placed in a wedge-shaped chamber, one side of which is stationary and the other side movable, the movement being imparted to the latter by a walking-beam. i

In the present invention improved results are obtained, iirst by forming the crusherplates which constitute the sides of the wedgeshaped chamber with sei-rations of laterallyextending ribs adapted to engage with the fragments of rock and to hold the same from slipping duringI the crushing operation.

A further improvement is that the movable pressure-plate is longitudinally reciprocated by engagement with rocking bearings in constant fixed relation to each other, said plate being deflected laterally during its longitudinal reeiprocation by a cam-bearing'.

As shown in the drawings, the frame of the.

machine comprises the vertical standards A, arranged in pairs, which are cross-connected to each other by the bars B, bolted or otherwise secured to said standards. The pairs of standards are secured to each other by longitudinal plates C, bolted thereto, said plates having inwardly-projecting portions u, which form bearings for the lower end of inclined side plates D. These plates D bear at their upper ends against the inclined bearing on the standards.

E represents end plates, which are bolted to the ends of the plates D, and together .that it is moved longitudinally. C :deflection is permitted by reason of the hinge therewith form a hopper or receptacle for receiving' the material to be crushed.

Centrally of the cross-bars B are formed the bearings F, having' a shaft (i journaled therein in the central plane of the machine.

H represents bearings formed on the end plates E, in vertical alinement with the bearings F, and adapted to receive the rock-shaft l. Shafts and I, between their respective bearings Fand Il, are partially eut away, as shown in Fig. 3, to form bearings for the reciprocating pressure-plates These members I in normal position are arranged in parallelism, and arranged thereabove are struts c. The struts c have formed at the upper ends the rounded rib w, which engages with a corresponding' socket formed in the lower face of the shaft I. The lower end of the portion c has a similar engagement with the upper end of the member (I. Thus the shaft I is free to be rocked through a limited angle, and in so doing' will impart a' vertical reciprocating movement to the member the rib (f turning in its socket. The lower member l is grooved and rests upon a ribf on the shaft K represents rolls extending beyond the members Il, said rolls being'` journaled at their ends in the end plates E.

,r/ represents cams formed on the inner faces of the member d, which are adapted to engage with the rolls I( in the reciprocation of the members (l, so as tocause a lateral deflection of the said members d at the same time This lateral connection e' between the members o and The members (Y have formed on their outer faces the laterally-extending serrations /zf. L represents stationary Crusher-plates, which are provided with corresponding seri-ations f, said plates being seated upon the plates D and extending at their lower ends in proximity to the members (Y.

U represents walking-beams arranged upon opposite ends of the shaft I adjacent to thev walking-beamsM and the free end of the rockarms N are cross-connected by shafts O.

P is a crank-shaft journaled in bearings upon the standards A at one side of the machine.

Q, is a connecting-rod extending from the crank to the shaft O of the adjacent end of the walking-beams. R is a similar connecting-rod connecting the shafts O at the opposite ends of said walking-beams and of the rockarms N.

The machine being constructed as described, in operation rotary motion is imparted to the crank-shaft P by any suitable drive connection. The rotation of the crank causes the reciprocation of the walking-beam through the connecting-rod Q, and a similar reciprocating movement is imparted to the rock-arm N by the rod R. Thus both the shaft 1 and the shaft Gr are rocked. The rocking of the shafts I and G will cause the opposite Vertical reciprocation of the plates CZ, one being moved upwardly, while the other is moved `downwardly. This vertical reciprocation will cause the cams g to travel on the rolls K, with the result that the members d will be deflected laterally toward the inclined Crusher-plate L. The fragments of rock to be crushed are iirst thrown into the hopper or wedge-shaped receptacle formed byL the plates D and E and will drop therein into the space between the plates L and the member d. Here in the reciprocation of the membersl d the serrations thereupon will engage'with the rock, drawing the same downward and also pressing it outward against the plate L. As this movement contracts the space in which the rock is held, it will cause a crushing of the latter. In the reverse movement of the member d the serrations thereupon will be moved to gain a new hold upon the crushed fragments of rock, so that in a succeeding downward movement they will be still further crushed. The result is 'that the rock is broken into smaller and smaller fragments until the lower end of the wedge-shaped chamber is reached. Here the crushed fragments will pass between the adjacent parallel faces j and 1, respectively, on the members CZ and the plate L. These faces are caused to approach and recede from each other by the rocking of the shaft Gr. Between Vthese faces the fragments crushed in the wedge-shaped chamber are given the final crushing, which will reduce them to powder.

What I claim as my invention is* 1. An ore-Crusher comprising a pair of rockshafts connected for synchronous movement, a crushing-plate, a strut, one end of the plate and strut pivotally abutting, and the opposite ends pivotally engaging bearings upon said rock-shafts whereby said plate may be reciprocated, a cooperating stationary plate arranged at an angle to said movable plate to form a Wedge-shaped chamber therebetween, and a cam in rear and intermediate the pivotal bearings of said reciprocating plate adapted to cause a lateral deflection thereof during the longitudinal movement.

2. An ore-crusher comprising a pair of rockshafts connected for synchronous movement, a crushing-plate, a strut, one end of the plate and strut pivotally abutting and the opposite ends respectively engaging bearings upon the rock-shafts whereby said plate may be reciprocated, a cam on the rear of said plate intermediate its bearings, a bearing with which said cam engages to laterally deiiect said plate during the longitudinal movement thereof, and a stationary cooperating plate arranged in front of and at an angle to said movable plate to form therebetween a wedge-shaped chamber.
